Application October 3, 1947, Serial No. 777,793

1 Claim.

My invention refers to container covers, and particularly to that type such as described in Patent No. 1,776,599 filed February 18, 1929, Serial No. 341,002.

The object of my present invention is to provide a simple construction of cover having a provision for closing and locking the same to effect an air tight seal and also to selectively release the cover.

A further object is to provide means for selectively releasing the cover or to loosen the same, whereby it is held in a partially suspended position to permit Ventilating the contents of the container.

A still further object is to provide a structure of cover wherein all of the parts are ush with or below the top plane of the same, whereby no obstructions are presented and containers may be stacked one upon the other.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the drawings,

Figure l represents a fragmentary view of a neck portion of a cover mechanism embodying the features of my invention, the parts broken away and in section to more clearly illustrate the structural features.

Figure 2 is a longitudinal sectional view of the same, the section being indicated by line 2-2 of Figure 1.

Figure 3 is a detailed face view of the Wing portion of a controller bail, the same being partly in section as indicated by line 3-3 of Figure 2.

Figure 4 is a fragmentary plan View of the cover portion and associated bail Wing.

Figure 5 is a plan sectional view through the container neck cover and one of the bail wings.

Referring by characters t0 the drawings, l indicates the mouth neck of a container, the same being shown in connection with a milk can.

The mouth of the neck I has fitted therein a slightly tapered slip cover 2 having an exterior annular bead 2' extending about its circumference slightly below the top edge of said cover, the bead being shown as engaging the upper edge of the mouth neck, whereby said mouth is frictionally and firmly closed, it being understood that the cover is provided with a suitable handle 3, whereby it is properly manipulated.

Projecting from the neck I is a pair of aligned pivot pins 3-3, which'pivot pins are rigid with vertically positioned offset spreader strips 4-4 brazed or otherwise suitably secured to the neck.

Pivotally mounted upon the studs or pins 3 are the lower terminals of a yieldable bail 5. Each terminal of the bail 5 has formed thereon a pair of oppositely extending wings 5.

One wing of each pair of wings 5 carries an inwardly directed roller 6. These rollers 6 as shown in Figure l engage the upper surface of the cover bead 2 when the bail-5 is swung down on one side of the neck.

The other wings of the pair of wings have inwardly extended therefrom eccentric cam flanges 'I--1, and the edges of said eccentric flanges are formed with spreader wedges 1', which wedges when the bail is swung from left to right engage the raised strips 4, whereby the wing portions of the bail are sprung outward as indicated by dotted lines in Figures 4 and 5 of the drawings.

Due to this spreading of the bail wings, it will be noted that the pressure rollers 6 are forced outwardly whereby they will clear the cover bead and permit the wings and associated bail to rotate freely in a downward direction clear of the bead, the position being indicated in dotted lines, Figures 1, 4 and 5. After the wing rollers are freed from the cover bead it should be noted that the eccentric cam flanges 1 will engage said bead and bodily lift the can cover from its seat, as indicated in dotted lines, Figure 1.

Hence, when the cover is so lifted from its seat is will break the seal of said cover and permit ventilation of the container contents, and

also the cover can be thereafter conveniently removed. It should be understood that the pivot pins 3 are of sufcient length to permit expansion or outward movement of the wings, whereby the rollers are cleared of the cover bead. It follows, after the bail is moved from left to right, as indicated in dotted lines Figure 1, and the cover is removed, it can be manually replaced, whereby its flange will close upon the upper edge of the container neck, and thereafter to lock it in said closed position, the handle is reversed in its action, being swung from right to left, whereby the rollers will again be sprung outwardly to clear the same from the cover bead as they rise to assume their position of engagement with said bead, at which time they will spring back into their locking position, as best indicated in Figure 2 of the drawings.

It should be noted that the upper rim of the cover and associated parts are all upon a common plane, whereby containers may be stacked one upon the other.

I claim:

In a container having an entrance neck and a cover slidable in the neck, said cover having an annular outstanding bead adapted to t against the upper Ledge of the neck when ,the cover is v:inserted inthe neck; a combined latch and lifter for the cover comprising a swinging U-shaped yieldable bail pivoted to the neck, `a pair of oppositely extending wings formed ,on each terminal of the bail on opposite sides of the pivotal point of the bail, aa 'CSN/:er bead engaging member on one wing of each :pair lof wings, said members being adapted toengage the upper surface of the bead when the bail is swung down on one side of the neck, inwardly Kdirected arcuate cam anges formed on the other wings l-Qf .the pair of -wmasadapted to .engage the lower Surface 0f the bead :when the .bail i-isswung on the other .Side 0f the neck, ,laterally projecting 5grail spreader str-ips 91,1 the v,opposite .sides of 4.the
